wmtow mm SPECIFICATION forming part of Letters Iatent No. 510,530, datedDecember 12, 11893.

Application filed November 30, 1892- Serial No. 33,601. (No modeLl Toall whom it may concern: Be it known that I, J QSEPI-I DOVER, a citizenof the United States, residing at Souderton, in the county ofMontgomery, State of My invention relates to window screeus adapted towindow frames, and has for its object to provide a more durable andefiicient screen and one which can be located fixedly within the guideways of the window frame,

beneath the outer sash and locked in position frame I prefer to employthe construction fshown inthe drawings, as the same serves also therein,and having a supplemental'frame which may be opened without disturbingthe main frame, and which will thereby permit of the raising andlowering of the front sash, and the closing and opening of the outsideshutter without removal of the screen from the sash frame.

To these ends my invention consists of a screen constructed with adouble frame, the outer frame adapted to be fixed immovably under theouter sash of the window in the usual guide ways of the frame thereof,with looking devices to secure the same in position therein, incombination with a pair of inner and supplemental screen frames whichare hinged to vertical portions of the outer frame above and below acentral horizontal cross piece which extends from one of said verticalportions of the outer frame to the other;

also in minor details of the construction as hereinafter set forth.

In the accompanying drawings illustrating my invention, Figure 1 is afront elevation of a window frame with my improved screen in positiontherein, held in place by the lower edge of the outer sash. Fig. 2 is avertical sectional View through the line 1-2 of Fig. 1. Fig. 3 is alateral sectional View through the line 3-4 of Fig. 1. Fig. 4 is anelevation of the screen, detached from the window frame.

The invention is capable of use with the ordinary window frame composedof a pair of sashes A, B mounted in vertical guide ways 0, D, (see Fig.2) and the outer frame a of the screen (Fig. 4.) is adapted to fit inthese guide ways and is held tightly therein way 0 of the window-frame.

under the outer sash A, by means of the turn buckles or other equivalentlocking devices, g, g, which fit into the guide ways of the window framethe lower edge B of the sash A resting upon the top edge of the mainframe a of the screen. The screen is composed of a main frame a,provided-with an additional central longitudinal cross-piece c, and withturn buckles h, h, on the side pieces of the frame, operating to lockthe hinged supplementalt'rames d, d. These two supplemental screenframes d d are covered'with wire or other screen netting, and are.hinged to the main frame so that they may swing inward and toward eachother. 1

For pivoting the frames 61 d to the main to strengthen and brace boththe main and hinged frames. A long plate sis placed upon the main frameopposite each end of the cross piece 0 and extending a short distance oneach side of the same and is secured to the frame above and below thecross piece. These plates are provided with transverse recesses n.Pieces m made of angular form and provided with gudgeons or pintles toengage the recesses of the plate 3 are secured to the corners of theswinging frames. The angular construction permits the piece or plate nto be secured to the side and end bar of the frame at each end and thisbraces such frame and materially strengthens the same. The plate 8 alsoserves to strengthen the main frame at a very important part where itreceives its greatest strain and is most liable to break.

The screen frame a is fitted in the guide way 0 of the outer sash, whichlatter rests upon it to hold it in position, aided by the turn buckles gwhich rest in the usual guide Thus it will be observed that the innersash B may be raised or lowered without disturbing the supplementalscreen frames. Itis also obvious that both the upper hinged supplementalscreen frame 01 and lower hinged supplemental screen frame at, oreither, independently of the other, may be swung open at pleasure toenable the shutters E to be opened or closed without disturbing orremoving the screen frame a from the window frame.

I am aware that it is not new to make a double frame screen, with theinner frame hinged to the outer, but such has always been made to coverthe whole window frame and is impracticable for the purposes of myinvention, and I disclaim the same; my screen differing therefrom inbeing adapted to fit in the guide ways of the window sash and held inposition therein by locking devices, and beneath the outer sash, therebyenabling the front sash to be lowered and the window wholly closed ifdesired without disturbing the screen and in enabling the user to openthe screen by supplemental hinged frames to admit more light and air orto close the shutters.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. A window screen consisting of a frame proper adapted to be fitted invertical guide ways, of a window frame with means to secure the sametherein, in combination with a pair of supplemental screen frames hingedto the main frame, and adapted to be swung inwardly thereon, withdevices to lock them in a closed position; substantially as described.

2. A window screen consisting of a main frame adapted to be fitted inthe guide ways of a window frame, having devices, such as turn buckles gg, to secure the same therein, said main frame being provided with acentral horizontal cross piece a, and a pair of supplemental screenframes (1 d, hinged to said main frame above and below the cross piece 0respectively, to adapt them to be swung toward each other, andmeans,such as turn buckles h h, to secure said hinged screenstemporarily in position in the main frame, substantially as described.

3. A window screen consisting of a main frame provided with the centralcross piece, a plate secured to the said main frame at each end of thecross piece above and below the same, a supplementary frame havingplates secured to two parts of the frame and provided with pintlesengaging recesses in the plate on the main frame, substantially asdescribed.

4. The herein described window screen consisting of a main frame,provided with a central cross piece, a plate secured to said frame ateach end of the cross piece above and below the same, the said platehaving recesses at each side of the cross piece to receive pintles, twosupplementary frames, each pivoted by two plates provided with pintles,said plates being each secured to two parts of the supplementary frame,substantially as described.

In testimony whereof I have hereunto affixed my signature this 21st dayof November, A. D. 1892.

JOSEPH DOVER.
